Specification of Letters Patent.

1?etented Bee. 537B, 191% To all whom it may concern:

Be it known that 1, ROBERT L. FRINK, of Bellevernon, Fayette county, Pennsylvania, have invented it new and useful (,reneMechanism, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is :1 side elevation of crane mechanism embodying my invention illustrating the some as used for handling drawn glass cylinders; Fi 2 is an enlarged side view of the cylinder ole their operating mechanism; Fig. 3 is an end view of the some Fig. 4 is a plan view of the some; Fig. 5 is on end elevation of the movnble carriage and the parts carried thereby;

Fig. 6 is 0. plan view of the same; and Fig. 7 is an enlarged side view of a portion 'of the crane mechanism.

My invention has relation to crane mechanism which has been especially designed for use in handling drawn glass cylinders, but which is useful for various other purposes, as will be readily understood from thefpllowing description My invention consists in the novel construction, arrangement and combination of parts all' substantially as hereinafterdescribed and pointed out in the appended claims.

In the drawings, thenumerel 2 designates the bridge .ofo crane which is movable on the tracks 3, and on hich is mounted a transversely-nmvable carriage 4-. Pivoted at 5 to 2 depending portion 4 of the frame of the carriage 1 is e leveror lever frame 6, to the outer end portion of which is pivoted at 7 a. lifting beam 8. The opposite end of the lever frame 6 is counterweighted as shown at 9 9, and also carries two sector gears 10, the teeth of which mesh with pinions ll'on a shaft 12 mounted transversely in the crane carriage 4. The shaft 12 is arranged to be rota/ted by means of a. motor 13 mounted on the (nirriage 4, through the worm gear connections .14. Journaled in the lever frame 6 is .a longitudinal screw shaft 15 on which is mounted a movable head 16 connected by a lifting beam 8.

4 18 supported by the lever frame 5.

Journcled in bearings 18 carried by a frame 19 at the end of the lifting beam 8 are porting are connected by toggle links 24. which has a screw-threaded connection inping or carrying devicesn'nd perntus, and transferring it to shown'by the dotted lines in tor 15*.operet1ng through the screw shaft '15 lever frame 6, are of sufiicient two vertical rock shafts 20, to which are secured the clamps 21 which are designed to embrace the drown glass cylinder indicated at A in Fig. 1. This cylinder shown as suspended above a gloss pot B of glass drowing apparatus C. The clamps 21.consist of frame portions 21 having grips 22 which are preferably composed of pieces of flexible es bestos wire cloth, or other yield ng material of a refractory nature. T he rock r shafts 20 with a shaft 25, which is journnled on. the lifting boom 8, end 18 coupled st .Zdto en nctueting motor 27 which is also mounted on said beern.

Supposing the mechanism described to be used forthepurpose of :removing'thc drewn glass cylinder 1E1 ,froin'tho glass drawing sp any desired part of the factory, and lacing it hori zontalposition, the operation is follows:- The parts being in the position shown in. Fig. 1, the motor 27 is started, thereby ne tuating the shaft 25 and moving the nut 24 to thereby, through the toggle linlrs 23, close the gripping jaws 21 upon the n linder A; The cylinder is now supported by the lifting beam 8 and lever frame 6, andunuy be disconnected from the drawing apparatus, and the crane bridge 2 moved to any desired position on the trucks 3. By now operating the motors 13 and. 15*, end st'the seine tiine 23 with a nut moving the carriage t beclm'erdly on the crane bridge 2, the cylinder may be turned into horizontsl position and lowered, as 1, the no.0

to move the head 16 to thereby swing the lifting beam 8 units pivots 7, while the op erection of the motor 13 swings the entire mechanism upon the center 5, eswill be readily understood. The coui'iterweights 9 which are connected to the lfilti end of the vi eight to practically counterbalance the weight of the arms 6, 8, 17, and of the gripping mechanism together with the weight of the lifting beam 8 and the parts carriedv thereby.

It will be apparent that instead of providing the lifting beam 18 .With the gripping mechanism especially redepted for demo and holding drown glass cylindess, the isfiil beam me be provided with-lifting or ovices of various kinds to sdspt the mechanism for use in handling various between the motor and the beam for swing 66 objects which it is desired to move from one position to another.

The advantages of my invention consist in the simplicity of the construction, and in the ease and rapidity with which the objects to be handled may be taken hold of and carried and moved into any desired position,

Various changes may be made in the details of construction and arrangement of the parts without departing from the spirit and scope of my invention, since IVhat I claim is:

1. In crane mechanism, a movable carriage, a jointed lifting and carrying device pivoted to the carriage arranged-to engage a vertical cylinder or similar object, means for moving said device upon its pivot to bring the cylinder into horizontal position, and means for separately moving one of the jointed members of said device; substantially as described.

2. In crane mechanism, a movable crane bridge, a carriage mounted for transverse movement on the bridge, a lever frame pivoted to the carriage, a lifting beam ivoted to the lever frame and having mec anism for engaging a vertical cylinder or similar object, and means for actuating said crane and beam, and also for moving the carriage; substantially as describcd.

3. In crane mechanism, a movable carriage, a lever f;ame pivoted thereto, a lifting beam pivotally connected to the lever frame and having mechanism for engaging a vertical cylinder or similar object, and means for separately actuating the frame and beam; substantially as desciibzd.

4. In crane mechanism, the combination with a movable carriage of a pivoted and jointed lifting frame carried thereby said frame having means for engaging a vertical cylinder or similar cbiect, and means for swinging the frame to lower the object into horizontal position; substantially as described.

5. ln crane mechanism, the combination with a movable crane bridge, and a carriage movable on the bridge, of acounterweighted jointed lifting and carrying device pivoted to the carriage,- and means for actuating the same; substantially as described.

6. In crane mechanism, a carriage, a counterweighted lever frame pivoted to the carriage, a motor geared to said frame, a lifting beam pivoted to the lever frame, and a mo.- tor for moving said beam; substantially as described. n V

7. In crane mechanism, a carriage, a-lever pivoted thereto to swin ina vertical plane, a motor geared to said ever, a lifting beam pivotally connected tothe lever and having grippers arranged to engage a vertical cylmdsr, a motor, and operating connections ing the beam independently of the lever; substantially as described.

8. In crane mechanism, a carriage, a lever pivoted thereto, a motor device for actuating the lever, a lifting beam pivotally connected to the lever and having grippers arranged to engage a vertical cylinder, a motor carried on the lever, and connections between the motor and the lifting beam; substantially as described.

9. In crane mechanism, the combination of a carriage, a lever pivoted thereto and having a counterweighted end portion carrying toothed sectors, a motor geared to the sectors, a lifting beam pivotally connected to the opposite end portion of the lover, a motor mounted on the beam, a movable cross-head actuated by the motor, and a connection between the head and the lifting beam; substantially as described.

10. In crane mechanism. a. pivoted lifting beam and means for actuating it, a support mounted on said beam at an angle thereto, and clamping devices on said support adapted to engage a vertical cylinder, sub

stantially as described.

11. In crane mechanism, the combination I of a pivoted lifting beam and means for moving the same, of pivoted clam s carried by a su port extending at an ang e to and mounte on the beam, and-means for opening and closing the clamps; substantially as described.

12. In crane mechanism, the combination with a lifting beam and means for actuating thesame, of pivoted clamps carried by the beam, and having yielding clamping members; substantially as described.

13. In crane mechanism, the combination with a lifting beam and means for actuating the same, of rock shafts carried by the beam, a motor supported on the beam, connections between the motor and the rock shafts, and clamps carried by-the rock shafts; substantially as describe 14.
